address issue #53 plus more for getDouble, putDouble, getString, putDouble, etc #55

Closed mrkraimer closed 5 years ago

mrkraimer commented 5 years ago

Changes have been made for getDouble, putDouble, getDoubleArray, putDoubleArray, getString, putString, getStringArray, and putStringArray.

1) Previously each only had support for a top level field named value. Each now allows access to a single sub field that has the correct type. Thus pvRequest must select a single field. For example

   pva->channel("PVRdumbPowerSupply")->putDouble(1.0,"power.value" );

2) PvaChannel now has a method for each of the above. For example instead of 

   PvaClientChannelPtr channel = pva->channel("PVRdouble");
   PvaClientPutPtr clientPut = channel->put();
   PvaClientPutDataPtr putData = clientPut->getData();
   putData->putDouble(1.0); clientPut->put();

now it can be

 pva->channel("PVRdouble")->putDouble(1.0 );

3) getDoubleArray and putDoubleArray work with any numeric scalar array

4) getStringArray and putStringArray work with any scalar array.
